This is a wildly good point. Vijay Gill did an analysis of AOL's Nx10G backbone network which he presented at a NANOG a while back, and it transpired that the overwhelming majority of customer-affecting outages were due to operator error, rather than equipment or circuit failure.
We had a presentation from a high availability specialist from (unnamed vendor) who showed very similar results. I was surprised at the actual numbers. The N.A. 'operator error' percentages were VERY much higher than ours, at least for what I'd call the core. I'm not trying to blow my own trumpet here. While I'd be flattered to think that we employ the best people, we are not somehow magically *that* superior to the N.A. telcos. Upon analysis, it looks like what we do differently is that we've rigorously eliminated complexity from parts of our network, (precisely to address this issue). -- Michael Newbery IP Architect TelstraClear Limited Tel: +64-4-920 3102 Mobile: +64-29-920 3102 Fax: +64-4-920 3361
